Abstract
The utility model relates to a vehicle braking booster pump, and belongs to the technical field of braking of engineering machinery. The vehicle braking booster pump is characterized by comprising an air chamber cylinder body with an air chamber, and a hydraulic cylinder body with a hydraulic chamber, wherein the air chamber cylinder body and the hydraulic cylinder body have round sections, are connected through connecting pipes and are fixedly locked with the connecting pipes through bolts. According to the vehicle braking booster pump, the air chamber cylinder body and the hydraulic cylinder body are connected with the connecting pipes through the bolts, and sealing rings are added, so that the phenomenon that the air chamber fails due to dust pollution is effectively avoided, sealing performance is improved, the service life is prolonged, and the operation safety factor is improved.
Description
Technical field
The utility model relates to a kind of car brakeing booster pump, belongs to the braking technology field of construction machinery and equipment.
Background technology
The air booster pump, in actual use, because the bad working environments environment of loader, frequent braking requires high to this reliability of products.Existing air booster pump, directly welding between its air chamber cylinder body and the hydraulic cylinder is because through being welded to connect, being prone to cause can't tight seal.
Summary of the invention
To the problems referred to above that exist in the prior art, the utility model provides a kind of sealing property good car brakeing booster pump.
The technical scheme that the utility model adopts is following:
A kind of car brakeing booster pump; It is characterized in that; Comprise the air chamber cylinder body that is provided with the air chamber cavity, the hydraulic cylinder that is provided with hydraulic chamber; Said air chamber cylinder body and hydraulic cylinder cross section are all rounded, and said air chamber cylinder body is connected through connection pipe with hydraulic cylinder, and said air chamber cylinder body and hydraulic cylinder are respectively through bolt and connection pipe fixing and locking.
Further, be provided with seal ring between said air chamber cylinder body and the connection pipe.
The utility model car brakeing booster pump, air chamber cylinder body and hydraulic cylinder and connection pipe adopt bolted connection, and increase seal ring; Prevented that effectively air chamber lost efficacy because of contamination by dust; Thereby the raising sealing property increases the service life, and improves the safety of operation coefficient simultaneously.
Description of drawings
For the ease of it will be appreciated by those skilled in the art that utility model is further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model.
The specific embodiment
See also Fig. 1, a kind of car brakeing booster pump comprises the air chamber cylinder body 6 that is provided with air chamber cavity 1, the hydraulic cylinder 3 that is provided with hydraulic chamber 4, and piston places in the hydraulic chamber 4.
Air chamber cylinder body 6 is all rounded with hydraulic cylinder 3 cross sections, and air chamber cylinder body 6 is connected through connection pipe 7 with hydraulic cylinder 3, and air chamber cylinder body 6 passes through bolt 5 and connection pipe 7 fixing and lockings respectively with hydraulic cylinder 3.
Simultaneously, be provided with seal ring 2 between air chamber cylinder body 6 and the connection pipe 7.
Above content only is to be given an example and explanation to what the utility model structure did; Under the technical personnel in present technique field described specific embodiment is made various modifications or replenish or adopt similar mode to substitute; Only otherwise depart from the design of utility model or surmount the defined scope of these claims, all should belong to the protection domain of the utility model.
